Serum adiponectin levels in patients with coronary artery disease
Journal of Ayub Medical College, Abbottabad : JAMC
Adiponectin is an adipocytokine secreted from white adipose tissue. Serum level of adiponectin has been shown to be reduced in several disease states like obesity and diabetes. Hypoadiponectinemia has also been included in the list of newer risk factors for Coronary Artery Disease (CAD). In this analytical cross-sectional study serum adiponectin level was measured by Enzyme Linked Immunosorbant Assay (ELISA) in 60 cases of coronary artery disease (CAD) (both sexes, aged 40-60 yrs) and 60 healthy controls. Low levels of adiponectin were seen in CAD patients as well as controls. These levels were lower as compared to western standards. Our study conforms to the previous observation of lower serum adiponectin levels in South Asians compared to the western standards. Serum adiponectin level should be considered in the laboratory work-up of CAD patients.

Adiponectin plays important roles in the endocrine and cardiovascular systems, in fat and carbohydrate metabolism, and inflammation. In this study the relationship between adiponectin levels with the presence and severity of coronary artery disease (CAD) is evaluated. This was a cross-sectional study that enrolled 213 persons who referred for coronary angiography. One cardiologist reported the results of each coronary angiography by using two scoring systems [number of vessel disease (usual method) and Gensini scoring system]. Then, the relationship between adiponectin levels with the presence and severity of CAD as well as predictive factors for CAD were evaluated. There was a significant negative association between mean serum adiponectin levels and presence of CAD (P = 0.04) after adjustment for all conventional risk factors for CAD. Also there was a significant negative correlation between serum adiponectin levels and severity of CAD based on the usual method for reporting coron...
Association between plasma adiponectin levels and unstable coronary syndromes
European Heart Journal, 2007
Obesity is a risk factor for an acute coronary syndrome (ACS). The association between elevated body mass index (BMI) and ACS is independent of most traditional risk factors, suggesting a possible contribution of other body fat-related mediators. This study evaluated the association between adiponectin and ACS. Four hundred and ninety-nine patients undergoing coronary angiography were divided into a subgroup without (n = 331) and with ACS (n = 168). In multiple regression analysis, higher adiponectin levels were independently associated with a lower risk of ACS [odds ratio (OR) = 0.61; 95% CIs: 0.46-0.81; P < 0.001]. In contrast, a higher BMI, a history of myocardial infarction, C-reactive protein, and angiographic coronary artery disease severity were all associated with a higher risk. The greatest increase in risk for ACS was seen at adiponectin levels < or = 5.5 microg/mL. Higher plasma adiponectin levels are independently associated with a lower risk of ACS.

The existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (CAD). However, the results of the studies conducted hitherto on this subject are inconsistent. We sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of CAD in patients undergoing non-urgent coronary angiography. In 399 consecutive patients undergoing non-urgent coronary angiography for CAD survey, plasma adiponectin, triglyceride, total cholesterol, high-density lipoprotein and low-density lipoprotein cholesterol, and fasting blood sugar levels were measured and demographic characteristics such as age, sex, Body Mass Index, diabetes mellitus history, systemic hypertension history, and family history of CAD were collected. According to the angiography results, the patients were divided into two groups of CAD and non-CAD. The severity of coronary atherosclerosis in the CAD group was ...

Decreased serum adiponectin levels have been shown in patients with coronary artery disease (CAD). We evaluated the association between serum adiponectin levels and CAD severity on the angiogram. The study included 86 patients (70 males, 16 females; mean age 60 years) with angiographically documented CAD (=/>50% stenosis). The patients were divided into three groups according to the number of vessels affected; thus, 18 had single-vessel, 16 had two-vessel, and 52 had multiple-vessel disease. The severity of coronary lesions was assessed using the modified Gensini score. Serum adiponectin levels were measured in the CAD group and in a control group of 33 subjects (16 males, 17 females; mean age 54.8 years) who were found to have normal coronary arteries on angiography. The mean age, the number of male patients, and the number of smokers were significantly higher in the CAD group (p=0.01). Patients with CAD exhibited significantly lower serum levels of adiponectin compared to the c...
Implications of plasma concentrations of adiponectin in patients with coronary artery disease
Heart (British Cardiac Society), 2004
To investigate whether concentrations of plasma adiponectin constitute a significant coronary risk factor, with particular focus on the relation between plasma concentrations of adiponectin and the development of acute coronary syndrome (ACS). Plasma concentrations of adiponectin were measured in 123 patients with coronary artery disease (CAD) and in 17 control participants. Patients were divided into three groups according to condition type: acute myocardial infarction (AMI) group (n = 59), unstable angina pectoris (UAP) group (n = 28), and stable angina pectoris (SAP) group (n = 36). Plasma concentrations of adiponectin correlated negatively with body mass index (r = -0.18, p < 0.05), serum triglyceride (r = -0.25, p < 0.01), and fasting glucose concentrations (r = -0.21, p < 0.05), but correlated positively with age (r = 0.26, p < 0.01), high density lipoprotein cholesterol concentrations (r = 0.35, p < 0.01), and low density lipoprotein particle size (r = 0.37, p ...
Association of Adiponectin with Total Leukocyte Count in Patients of Coronary Artery Disease
Journal of Ayub Medical College Abbottabad, 2022
Background: Hypoadiponectinemia and raised total leukocyte count have been associated with coronary artery disease. The aim of this study was to investigate association of serum adiponectin levels with total leukocyte count in patients of coronary artery disease belonging to Khyber Pakhtunkhwa. Methods: This cross-sectional/analytical study consisted of two groups. Group A contained 100 patients of coronary artery disease while group B contained 100 healthy controls. Consent of the study subjects was obtained, their history was recorded and fasting blood samples were analyzed for serum adiponectin level, total leukocyte count (TLC), serum lipid profile which included serum total cholesterol (T-C), triglyceride level (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Adiponectin level was determined with ELIZA method, TLC was estimated on automated haematology analyzer and lipid profile was determined using enzymatic colorimetric method. SPSS version 21 was used to analyze the data. Results: Subjects with coronary artery disease when compared to healthy subjects showed significantly high level of total leukocyte count (9.26±1.488 vs. 6.37±4.052) and low level of serum adiponectin (4.3±0.80 vs. 9.6±3.69). Moreover, serum lipid profile showed low HDL-C (30.04±9.1 vs. 43.64±7.3) and rose triglyceride (220.1±67.7 vs. 181.86±41.4), total cholesterol (229.3±37.01 vs. 189.4±32.7), and LDL-C (153.78±38.53 vs. 109.16±33.91) levels. Significant negative association of adiponectin with TLC (r-0.826 with p<0.01) was observed in the study subjects. Conclusion: We observed elevated level of total leukocyte count and reduced level of adiponectin in subjects with coronary artery disease. Moreover, hypoadiponectinemia correlated negatively with TLC levels.

Adiponectin is an adipocytes-produced protein and showing a number of antiatherogenic effects. Adiponectin sems to be extensively deposited in the intersticium of venous lesions of persons with myocardial infarction. It may exhibit antiatherogenic and reparative effects. A decreased adiponectin concentration may be a risk factor of the origin and complications of atherosclerosis. Aim of the study: 1) Do the adiponectin concentrations in venous blood of persons with acute coronary syndrome (ACS) differ from those in persons with stress angina pectoris? 2) In these persons do adiponectin concentrations in venous blood differ from those in main coronary arteries? 3) Do adiponectin levels differ in the infarction and non-infarction arteries in persons with STEMI (ST Elevation Myocardial Infarct) and delay within 4 hours after the onset? 4) In persons with ACS does any correlation exist between venous adiponectin and common risk factors of cardiovascular complications? Adiponectin concentration was determined in samples of blood collected from the peripheral vein and during coronarography in various localizations in 4 groups of examined persons (I.-no signs of CAD, II.-stable stress angina pectoris, III.-ACS over 48 hours without elevations of ST segment, IV.-STEMI during first 4 hours after its origin and proved occlusion of coronary artery at coronarography). Coronary angiography, risk factors and anamnestic data were analyzed. The software Medcalc was used to perform statistical analysis. We examined 73 probands with signs of myocardial ischemia (mean age of 61.5 years, 64 % males), who were subjected to coronarography and 21 healthy volunteers. A mean delay (delay from the origin of complaints to the performed coronarography) was 3.1 ± 0.5 hours in individuals in the group IV. In patients with ACS we found lower adiponectin concentrations in venous blood compared to healthy individuals and persons with stress AP, but changes were not statistically significant (I.:-5.9 ± 2.7 ng/l, II.:-4.9 ± 1.2 ng/l, III.:-5.2 ± 4.1 ng/l, IV.:-4.6 ± 2.7 ng/l); no differences were found also with BMI. No significant difference was recorded between the samples of venous blood and those of coronary arteries, nor between the infarction and the non-infarction arteries in the group IV. (5.2 ± 2.6 ng/l vs. 4.8 ±-2.7 ng/l). Significant negative correlations were observed between adiponectin concentrations and BMI (correlation coefficient-0.29), triacylglycerols (correlation coefficient-0.4), AOPP (correlation coefficient-0.39), and positive correlations with HDL (correlation coefficient 0.32). No correlation was recorded between adiponectin and CRP. Adiponectin concentrations in persons with ACS are lower than in healthy persons or patients with stable angina pectoris, but differences are not statistically significant. The absence of adiponectin differences between the infarction/non-infarction artery may support the hypothesis of adiponectin uptake in the ischemic lesion with subsequent decrease in blood adiponectin. On the contrary, adiponectin decrease may be a risk factor independent of the origin and development of ACS.

Objective: Adiponectin has anti-atherogenic properties and low circulating adiponectin has been linked to coronary atherosclerosis. Yet, there is considerable evidence that the high-molecular weight (HMW) complex of adiponectin is the major active form of this adipokine. We therefore investigated whether HMW adiponectin is associated with the extent of coronary artery disease (CAD) in men. Research design and methods: Associations among CAD, HMW adiponectin and the HMW/total-adiponectin ratio were assessed in 240 male patients undergoing elective coronary angiography. Total adiponectin and HMW adiponectin was measured by enzyme-linked immunosorbent assay and serum levels were correlated with defined coronary scores and established cardiovascular risk factors. Results: We found significant inverse correlations between angiographic scores and HMW adiponectin [Extent Score (ES): r = −0.39; Gensini Score (GS): r = −0.35; and Severity Score (SS): r = −0.40, all P < 0.001], and the HMW/total-adiponectin ratio (ES: r = −0.49; GS: r = −0.46; SS: r = −0.46; all P < 0.001).
